Will the manufacturer of your super secret machine give you their supplier's contact info? -

Hurco BMC30 problems with SW2018
I get programming offline, and using CAM for complicated part contours or better control of dynamic tool paths, but this is a 24+ year old HURCO. Why are you not using the ultimax software? From your post it looks like you are drilling holes. And why the canned cycles? Unless you are changing...- bigjon61

HEAVY 1949(?) National brand machinist's tool chest..
Pictures are worth a thousand words, but if the box has been painted, worth whatever your local buy/sell/trade FB page is willing to pay.- bigjon61

Pull-Back v/s Dead Length Collet Chucks
Luckily they even offer it as an option. We probably have 300+ sets of pads across S-20 thru S-30, I couldn't imagine buying the quick change collets to replace all of them.- bigjon61

Has Anyone Had Luck With Staffing Agencies?
You're not gonna find good help from a staffing agency. The good ones have already gone through the staffing agency, got fucking burned by said agency, and vowed to never go through one ever again.- bigjon61

Pull-Back v/s Dead Length Collet Chucks
The S-26 Master also has the rubber. We paid $821 for one last spring for our new Lynx. I hate the work stop design.- bigjon61

Brand new machine tips?
Maybe not so much machine related, but watch this video below. While I never implemented any of the things in the video, it does kind of get you thinking outside of the box as far as work station design and setting up your work area.- bigjon61

Need help sourcing information for a German lathe
It says right there on the laser calibration tag "Niles Engine Lathe". Not sure what model but I imagine they are all at least similar. https://nsh-usa.com/about-nsh-usa/- bigjon61

Manual Lathe Recommendations
+1 for Acra. We still have one in our shop, but sold our 16x40 in favor of a Leblond Regal servo shift (turns out that was a bad restoration unit...). Us guys on the floor who were running it every day hated to see it go.- bigjon61

OT: Best steel toe shoes for everyday
Timberland. I like their Helix 6" work boots, but I have also had pretty good luck with their work shoes as well. 6'2 310lbs and they last me 18 months or close to 2 years. I have spent many 15+ hour days in them and they suit me fine. Your mileage may vary. -

Mill Guarding
I don't know why but OSHA has a basic training manual on operating a milling machine (actually I think it is originally a power point). https://www.osha.gov/sites/default/files/2021-04/Mill%20-%20Trainer%20Script.pdf Step 24, the manual makes mention of the magnetic chip shields. I think if... -

Shrinking ID.
It has to stop somewhere, or else the machine will run off the end of the ways. Figure out where it does stop and see if it goes back the other way.- bigjon61

Live tooling suggestions!
Our Hwacheon came with MD Tooling and at the recommendation of our salesman, bought Heimatec. Both perform better than the Eppingers our Doosans came with.- bigjon61

Lathe turret won't stay clamped
This problem hits wildly close to home. We have a Daewoo Puma with the Fanuc 18i that gave us indexing problems for years. Finally got a good tech out to look at it, and it turned out to be the I/O module (which I had suspected TWO YEARS PRIOR). Doesn't help your situation, but it looks like you...- bigjon61
